BRICK-MOLD.

SPECIFICATION forming part of Letters Patent No. 459,313, datedSeptember 8, 1891.

Application filed February 14,1891. Serial No. 381,428. (No model.)

To all whom it may concern:

Be it known that I, CHARLES E. SIMPSON, of Portsmouth, in the county ofScioto and State of Ohio, have invented a new and Improved Brick-Die, ofwhich the following is a full, clear, and exact description.

My invention relates to improvements in that class of brick-dies whichare used for pressing fire-brick, red brick, tiles, &c., into shape. Thelining is an important feature of such dies, as the lining wears outmuch faster than the body of the die, and it is necessary that it beconstructed in such a manner that it can be easily taken out, repaired,and replaced and the objects of the in vention are to provide aconvenient die in which the lining may be easily and firmly placed and alining specially adapted to its purpose.

To this end my invention consists in certain features of constructionand combinations of parts, which will be hereinafter fully described andclaimed.

Reference is to be had to the accompanyin g drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of the die. Fig. 2 is a vertical longitudinalsection of the same on the line :20 a: of Fig. 1. Fig. 3 is a brokencross-section on the line 3 y of Fig. 2. Fig. 4. is a detail sideelevation of one of the side lining-plates, and Fig. 5 is a detail sideelevation of one of the end lining-plates.

The body or frame A of the die is generally of a rectangular shape, isopen on opposite sides, and is provided on each side at the corners withprojecting flanges A, which are slotted, as shown at Fig. 1, and whichenable the die to be secured in a machine. In the inner face of thewalls of theframe are horizontal recesses a, and in the outer edge ofthe end portions of the frame are recesses a. The side lining-plates Bare of about the same length as the inside of the frame, the said plateshaving centrally, on one side, projectinglugs b, which fit loosely inthe recesses a of the frame, and the plates have on one edge alaterally-extending flange B, which is adapted to project over the outeredge of the frame, thus preventing the plates from being pushed inwardand which also serves to stiffen the plates. The end plates Cform thelining for the ends of the die, said plates having on one side a lug cto enter the recesses a of the main frame, and the end plates havingalso at one edge a flange O, which overlaps the outer edge of the frameand which is provided on the inner side with a lip 0, adapted to enterthe recesses a of the frame and prevent the displacement of the plates.

Then the plates B and O are to be inserted in the main frame A, they areground to the proper size, the plates B are inserted on the sides, andthe plates 0 at the ends, and the plates B and O are held in relation tothe frame, so that there will be space all around between thelining-plates and the frame, as shown in Fig. 2, and the lining-platesand the frame may be held in a desired position in relation to eachother by wedging them up with strips of iron, and ,when the plates areproperly placed some soft metalsuch as Babbitt, lead, or equivalentmaterial-which may be melted, but which will quickly harden, is pouredaround them and also into the recesses a. This material fills all theintervening space between the lining-plates and the frame, as shown at Din Fig. 3, and the molten material also runs into the recesses a, andafter it hardens thelining-plates will be firmlyheld in place. If it isnecessary to remove the lining-plates and replace them by new ones, theymay be removed by heating the die, so as to melt the material betweenthe plates and the main frame.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. A brick-die comprising a main frame havingrecesses in the side walls, lining-plates having lugs thereon to fit therecesses in the walls and having flanges to overlap the edge of the die,and a filling of easily-melted material between the lining and theframe, substantially as described.

2. A brick-die comprising a main frame having recesses in the side wallsand in the outer edge and a lining having lugs to enter the recesses andflanges to overlap the edge of the die, substantially as described.

3. A brick-die comprising a main frame having recesses in the side wallsand in the outer edge at the ends a lining composed of separable sideand end plates, said plates IOO side plates having projectinglugs ontheir outer sides and having flanges on one edge and end plates havinglaterally-extending lugs and having edge flanges with lips thereon, thelugs and lips being adapted to enter corresponding recesses in adie-frame, substantially as described.
